Abstract
OBJECTIVES Fever and increased inflammatory responses sometimes occur following endoscopic resection (ER). However, the differences in causes according to the organ are scarcely understood, and several modified ER techniques have been proposed. Therefore, we conducted a comprehensive prospective study to investigate the cause of fever and increased inflammatory response across multiple organs after ER. METHODS We included patients who underwent gastrointestinal endoscopic submucosal dissection (ESD) and duodenal endoscopic mucosal resection at our hospital between January 2020 and April 2022. Primary endpoints were fever and increased C-reactive protein (CRP) levels following ER. The secondary endpoints were risk factors for aspiration pneumonia. Blood tests and radiography were performed on the day after ER, and computed tomography was performed if the cause was unknown. RESULTS Among the 822 patients included, aspiration pneumonia was the most common cause of fever and increased CRP levels after ER of the upper gastrointestinal tract (esophagus, 53%; stomach, 48%; and duodenum, 71%). Post-ER coagulation syndrome was most common after colorectal ESD (38%). On multivariate logistic regression analysis, lesions located in the esophagus (odds ratio [OR] 3.57; P < 0.001) and an amount of irrigation liquid of ≥1 L (OR 3.71; P = 0.003) were independent risk factors for aspiration pneumonia. CONCLUSIONS Aspiration pneumonia was the most common cause of fever after upper gastrointestinal ER and post-ER coagulation syndrome following colorectal ESD. Lesions in the esophagus and an amount of irrigation liquid of ≥1 L were independent risk factors for aspiration pneumonia.

Abstract
BACKGROUND/PURPOSE Laparoscopic sleeve gastrectomy (LSG) is an effective treatment for patients with morbid obesity, but the optimal gastric volume (GV) for resection remains unclear. Accordingly, we aimed to determine the optimal percentage of excised stomach that could engender significant weight loss and improve fatty liver. METHODS This prospective study included 63 patients. Computed tomography (CT) scans were performed before and 1 year after LSG to evaluate the gastric lumen (GL) and GV. Specifically, the stomach was distended with effervescent powder, following water-contrast mixture (20:1) and assessed by three-dimensional reconstruction. The correlations of reduced gastric lumen/volume (RGL/RGV) with total body weight (BW) loss and liver-spleen density ratio (LSDR) changes were analyzed, and optimal RGL/RGV associated with significant BW and fatty liver changes were determined. RESULTS We noted a positive correlation between the percentage of RGV/RGL (%RGV/%RGL) and percentage of total weight loss (%TWL; r = 0.359, p = 0.004 and r = 0.271, p = 0.032). Furthermore, a %RGL value of >78.2% and %RGV value of >75.3% were associated with more significant BW loss than did limited excision (both p < 0.01). On the other hand, LSDR values increased significantly after LSG, corresponding to the improvement of fatty liver disease at %RGL and %RGV values of >59.1% and >56.4% (both p < 0.01), respectively. CONCLUSION %RGV and %RGL were determined to be factors affecting LSG outcomes. LSG engendered significantly more BW loss when %RGV was >75.3% and resulted in fatty liver disease improvement when %RGV was >56.4%.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure worldwide. Many factors have been investigated in the literature to predict weight loss outcomes after LSG. However, insufficient data regarding the resected stomach weight (RGW) exists. This retrospective study aimed to investigate the association between RGW and weight loss outcomes 1 year after LSG. MATERIALS AND METHODS Fifty-four patients who underwent LSG in a tertiary care center were evaluated retrospectively. The statistical analyses were performed to investigate the correlation between preoperative demographics, RGW, and the excess weight loss percentage (%EWL) and percent total weight loss (%TWL). RESULTS The mean RGW was 169.7±40.1, ranging from 101 to 295 grams. The RGW was significantly correlated with preoperative weight (r=0.486; P<0.001), body mass index (r=0.420; P=0.002), and age (r=0.327; P=0.01). However, RGW did not predict postoperative weight loss, as measured by percent total weight loss (%TWL) and percent excess weight loss (%EWL), respectively (r=0.044; P=0.75 and r=-0.216; P=0.11). Multiple linear regression analysis identified age as a negative predictor for both %TWL (β=-0.351, P=0.005) and %EWL (β=-0.265, P=0.03), while preoperative body mass index was a negative predictor for %EWL (β=-0.469, P<0.001). CONCLUSION The RGW, although correlated with patient characteristics, does not serve as a reliable predictor of postoperative weight loss in the first year after LSG. Further research is needed to improve predictive models and patient care in bariatric surgery.

Sleeve gastrectomy morphology and long-term weight-loss and gastroesophageal reflux disease outcomes. Surg Endosc 2023:10.1007/s00464-022-09555-6. [PMID: 36645483 DOI: 10.1007/s00464-022-09555-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 08/08/2022] [Indexed: 01/17/2023]
Abstract
BACKGROUND The relationship between sleeve gastrectomy (SG) morphology and long-term weight-loss and gastroesophageal reflux disease (GERD) outcomes is unknown. METHODS All patients (n = 268) undergoing SG performed by 3 surgeons at a single academic institution from January 1, 2010 to December 31, 2012 were included. Long-term weight-loss and GERD outcomes were available for 90 patients which were incorporated in analyses. SG morphology was determined from postoperative day 1 upper gastrointestinal series (UGIS) available from 50 patients. Images were independently categorized using previously published methodology as Dumbbell (38%), Lower Pouch (22%), Tubular (26%), or Upper Pouch (14%) by Radiologist and Surgeon. Radiologist categorization was used when disagreement occurred (8%). Univariable analyses were conducted to explore potential associations between SG morphology, weight loss, and GERD outcomes. RESULTS Follow-up was 8.2 ± 0.9 years. Population characteristics included age of 45.1 ± 10.8 years, female sex in 83.3%, and hiatal hernia repair (HHR) performed at index SG in 17.8%. Surgeons did not preferentially achieve a specific SG morphology. Changes from preoperative obesity and associated diseases comprised body mass index (BMI) (49.5 ± 7.6 vs. 39.2 ± 9.4 kg/m2; p < 0.0001), diabetes mellitus (30.0 vs. 12.2%; p = 0.0006), hypertension (70.0 vs. 54.4%; p = 0.0028), hyperlipidemia (42.2 vs. 24.2%;p = 0.0017), obstructive sleep apnea (41.1 vs. 15.6%; p < 0.0001), osteoarthritis (48.9 vs. 13.3%; p < 0.0001), back pain (46.5 vs. 28.9%; p = 0.0035), and medications (4.8 ± 3.3 vs. 3.7 ± 3.5; p < 0.0001). Dumbbell SG morphology was associated with lesser reduction in BMI at follow-up (--6.8 ± 7.2 vs. -12.4 ± 8.3 kg/m2; p = 0.0196) while greater BMI change was appreciated with Lower Pouch SG shape (-16.9 ± 9.9 vs. -8.4 ± 6.8 kg/m2; p = 0.0017). GERD was more prevalent at follow-up than baseline (67.8 vs. 47.8%; p < 0.0001). GERD-specific outcomes included de novo (51.1%), persistent (27.9%), worsened (58.1%), and resolved (14.0%) disease. Ten patients underwent reoperation for refractory GERD with SG morphology corresponding to Dumbbell (n = 5) and Upper Pouch (n = 1) for those with available UGIS. Univariable analyses showed that patients with GERD experienced a larger reduction in BMI compared with patients without GERD (-11.8 ± 7.7 vs. -7.0 ± 5.1 kg/m2; p = 0.0007). Patient age, surgeon, morphology category, and whether a HHR was done at index SG were not associated with the presence of any, de novo, or worsened GERD. Female sex was associated with worsened GERD (96.0 vs. 4.0%; p = 0.0455). Type of calibration device, distance from staple line to pylorus, and whether staple line reinforcement was used were not associated with SG morphology classification. CONCLUSION This is the first study assessing the impact of SG morphology on long-term weight loss and GERD. Our data suggest an association between SG morphology and long-term weight loss but not with GERD outcomes. Current technical standards may be limited in reproducing the same SG morphology. This information may help guide the technical optimization and standardization of SG. Surgeons did not favor a specific SG morphology (1). Our results signal to a relationship between radiographic assessment of SG morphology and long-term weight-loss outcomes with Dumbbell classification correlated with lesser reduction in BMI (2a) and Lower Pouch morphology associated with superior weight loss (2b).

Abstract
Purpose Long-term studies reported inadequate weight loss or weight regain after laparoscopic sleeve gastrectomy (LSG). This study investigated a possible relationship between preoperative gastric volume (GV) measured by CT volumetry and weight loss one year after LSG. Methods This prospective study included 120 patients scheduled for LSG. 3D CT gastric volumetry was done before surgery. The weight loss in the first year was serially recorded. The primary outcome measure was the correlation between preoperative GV and postoperative weight loss after one year. The secondary outcomes were the correlation between preoperative GV and other patients’ characteristics as age and body mass index (BMI). Results Weight and BMI decreased significantly up to 12 months. The percentage of excess weight loss (%EWL) at 6 and 12 months was significantly higher than at three months. Preoperative GV was 1021 ± 253, ranging from 397 to 1543 mL. GV was not related to sex, age, weight, height, postoperative weight, and BMI. Conclusion Preoperative gastric volume cannot predict weight loss one year after LSG. It is not correlated with age, sex, or preoperative weight, and BMI.

Abstract
INTRODUCTION Given its feasibility and efficacy, laparoscopic sleeve gastrectomy (LSG) has become a widely accepted bariatric surgery for patients with clinically diagnosed severe obesity. LSG induces anatomical changes and subsequent weight loss which may affect drug pharmacokinetics (PK) and consequently impact dosing regimens. This review aims to examine the effect of LSG on drug PK and identify relevant gastrointestinal physiological alterations. AREAS COVERED PubMed, Embase, Scopus, and the Cochrane Library were searched for articles related to drug PK and LSG from inception to July 2021. Moreover, literature concerning postoperative physiological conditions in the gastrointestinal tract, such as gastric pH, gastric emptying, and small bowel transit time, etc., which may affect the PK profile of drug products was also reviewed. EXPERT OPINION Although LSG is classified as having restrictive property without malabsorptive bypass, postoperative changes in gastrointestinal physiology and subsequent weight loss may also lead to increased, decreased or unaltered drug exposure levels. General monitoring on drug efficacy or safety using biomarkers is proposed. In addition, therapeutic drug monitoring for those drugs when it is applicable and available is recommended to ensure efficient drug dosing and avoid adverse effects. Further research into many individual drugs are warranted.

Abstract
In the XXI century obesity has become one of the most demanding epidemiological threats worldwide. At the same time, bariatric surgery has established itself as an effective treatment for morbidly obese patients, with laparoscopic sleeve gastrectomy (LSG) emerging as the most popular bariatric procedure. This paper reviews the role of imaging studies of patients after LSG. Computed tomography is widely considered as the method of choice in detection of complications in early postoperative period. The dynamic character of upper gastrointestinal examination allows for the assessment of passage through the gastric remnant. The paper also discusses evaluation of the shape and volume of the gastric remnant assessed by imaging studies.

Abstract
PURPOSE Laparoscopic sleeve gastrectomy (SG) is now frequently performed as a definitive bariatric procedure. The aim of the study was to evaluate the detailed morphology of remnant stomachs after SG with respect to volume and sleeve migration. MATERIALS AND METHODS We performed a review of prospectively collected data on patients that completed a 12-month postop examination, which included CT volumetry of the sleeve, and a questionnaire that addressed postop food tolerance. CT volumetry study included total sleeve volume (TSV), tube volume (TV), antral volume (AV), tube/antral volume ratio (TAVR), and the presence of intrathoracic sleeve migration (ITSM). RESULTS One hundred patients were included in this study. Mean %TWL (total weight loss) at 12 months postop was 31.1% (14.3~55.5), and mean TSV, TV, AV, and TAVR were 188.3 ± 67.3 ml, 81.3 ± 38.5 ml. 107.0 ± 45.1 ml, and 0.846 ± 0.514 respectively. TSV was not correlated significantly with %TWL at 12 months postop (r=-0.140, p=0.164). Thirty patients (30/100, 30%) showed ITSM. Patients with ITSM had a significantly lower mean GER score (5.9 ± 2.3 vs. 7.5±1.9, p=0.001), and a higher proportion showed suboptimal weight loss (43.3% vs. 15.7%, p=0.003). CONCLUSIONS Mean TSV was not found to be significantly correlated with %TWL at 12 months postop. The presence of ITSM indicated more frequent GER symptoms and a higher probability of suboptimal weight loss.

Singla V, Aggarwal S, Aggarwal S, Gupta M, Singh D. Correlation of weight loss with residual gastric volume on computerized tomography in patients undergoing sleeve gastrectomy: A systematic review. Clin Obes 2020; 10:e12394. [PMID: 32767720 DOI: 10.1111/cob.12394] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 06/08/2020] [Accepted: 07/07/2020] [Indexed: 12/19/2022]
Abstract
Laparoscopic Sleeve gastrectomy (LSG) is the most commonly performed bariatric surgical procedure worldwide. There is wide variation however in post-operative weight loss on long term follow-up, and residual gastric volume (RGV) is believed to be an important variable. Multiple studies have correlated RGV as assessed by Computerized Tomography volumetry with excess weight loss (EWL%) following LSG, but definite consensus is lacking. This article systematically reviews the published studies in English literature to ascertain whether any correlation exists between the RGV and EWL% following LSG. Ten studies were included in this review, and significant differences were noted in the technique of RGV assessment, and timing of RGV and EWL% assessment. Five studies found a statistically significant correlation between the RGV and EWL%. One study found a correlation which did not reach statistical significance. Two additional studies reported that the resected volume rather than RGV correlated with the EWL%. Meta-analysis of studies reporting correlation between RGV and EWL% showed that up to 26.3% (95% CI: 5.1%-56.1%) of variability in EWL% can be explained by variations in RGV. A lower RGV is likely to result in a better post-operative weight loss following LSG. There is need for standardization of technique and timing of RGV assessment.

Sleeve Volume and Preoperative Gastric Volume Assessment Using Three-dimensional MDCT Gastrography and Their Correlation to Short-term Post-Sleeve Gastrectomy Weight Loss. Obes Surg 2020; 31:490-498. [PMID: 33006088 DOI: 10.1007/s11695-020-05012-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 09/22/2020] [Accepted: 09/24/2020] [Indexed: 01/06/2023]
Abstract
PURPOSE Several factors including preoperative stomach capacity and sleeve volume impact weight loss after laparoscopic sleeve gastrectomy (LSG). We aimed at measuring these volumes using multidetector computed tomography (MDCT) gastrography and correlating them with postoperative weight losses. MATERIALS AND METHODS Morbidly obese patients prepared for LSG during 2018 were included in the study. MDCT gastrography was performed 1 week before, 6 and 12 months after LSG. Preoperative gastric volume and postoperative sleeve volumes were measured. Correlation with preoperative BMI and postoperative %TWL was performed. The change in sleeve volume at 6 and 12 months was assessed. RESULTS A total of 98 patients (62 F) were included. Mean preoperative BMI was47 ± 7 kg/m2. Follow-up was achieved in 89 patients (91%) and 82 patients (83%) at 6 and 12 months, respectively. Mean %TWL was 24 ± 3 and 32.8 ± 3 at 6 and 12 months, respectively (p < 0.05). Preoperative gastric volume ranged from 800 to 1800 ml (mean ± SD, 1310 ± 307) and dropped significantly to range from 140 to 170 ml (158 ± 9) and from 165 to 210 ml (181 ± 12) at 6 and 12 months postoperatively, respectively. Pouch was not significantly dilated at 12 vs. 6 months postoperatively. Preoperative gastric volume was significantly correlated with preoperative BMI (p = 0.006*) but not with postoperative weight losses. Correlation between postoperative pouch volumes and weight losses at 6 and 12 months postoperatively showed no significance. CONCLUSION Sleeve pouch is significantly smaller than preoperative stomach, but not significantly correlated to weight loss. Restriction is an important, but not the only factor controlling weight loss after LSG.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a safe and effective bariatric procedure in terms of excess weight loss. Nevertheless, controversies still exist on several technical and operative aspects of LSG. The aim of this study is to evaluate variations in anthropometric features in subjects with a LSG gastric resection starting from 2 cm or 6 cm from the pylorus. Secondary aim was the evaluation of differences in morbidity, food tolerance, and GERD incidence studied with upper endoscopy (UE) and GERD Health-Related Quality-of-Life score. METHODS Patients were prospectively randomized into 2 groups: Group A (at 2 cm proximally to the pylorus) and Group B (at 6 cm proximally to the pylorus). All patients were followed-up at 3, 6, 12, and 24 months. UE was performed in all patients at 12 or 24 months. RESULTS One hundred and fifty met the inclusion criteria and were enrolled in the study. The anthropometric features (BMI, %EWL, %TWL) resulted statistically different in the first 12 months (24.2 ± 3.4 vs 27.5 ± 4.3, 63.7 ± 14.1 vs 59.6 ± 12.5 and 42.9 ± 7.4 vs 38.2 ± 6.2), in favor of group A. At 24 months the differences disappeared (25.2 ± 4.4 vs 26.2 ± 3.3, 62.8 ± 13.1 vs 61.6 ± 10.5 and 41.9 ± 7.4 vs 40.2 ± 6.2). An increased GERD was found in both groups postoperatively with a higher incidence in group A at 6-month follow-up. CONCLUSION Performing the LSG with a radical antrectomy could improve weight loss at 12-month follow-up but expose to lower food tolerance and higher transitory GERD. The differences seem to be reduced to a 24-month.

Abstract
BACKGROUND Postoperative sleeve volume (SV) is a key factor in evaluating the results of laparoscopic sleeve gastrectomy (LSG). An objective measurement of SV was obtained with 3-dimensional computed tomographic (3DCT) reconstruction. Several studies have compared SV with percent excess weight loss (%EWL), identifying an inverse relationship. We hypothesized that gastric capacity is one of the factors responsible for weight loss after LSG. OBJECTIVES Outcomes of the study were the analysis of the inverse correlation between SV and weight loss (%EWL and body mass index) at the 12-month follow-up, and evaluation of SV in the group with %EWL >50%. In addition, the failure rate was quantified in the SV >180 mL group. MATERIALS AND METHODS This is a prospective study with the collection of data. All patients who received LSG from January to December 2017 were evaluated. Computed tomography was performed on the upper abdomen at 12 months postoperatively to measure the SV using a standardized technique involving gastric distension. RESULTS A total of 42 patients were considered for 3DCT evaluation at the 12-month follow-up. A significant linear inverse relation was reported between SV and %EWL (P<0.05); a similar trend, without significant results, was reported for body mass index loss. The entire cohort was subdivided according to %EWL. A %EWL<50% presented a significantly higher mean SV (P<0.01) than %EWL >50%. SV >180 mL was powerful in predicting abnormal gastric distension. Over this value, %EWL was lower than that in the remaining group (P<0.05, 31.9% vs. 51.8%). CONCLUSIONS Our results confirmed a direct relation between SV and %EWL. Objective evaluation of gastric compliance obtained with 3DCT should be used intensively for LSG.

Abstract
OBJECTIVE To study the relationship between the amount of surgery-induced gastric volume reduction and long-term weight loss and glucose tolerance. BACKGROUND DATA Vertical sleeve gastrectomy (VSG) has recently surpassed gastric bypass to become the most popular surgical intervention to induce sustained weight loss. Besides inducing significant weight loss, VSG also improves glucose tolerance. Although no clear correlation has been observed between the size of the residual stomach and sustained weight loss, this begs the question whether less aggressive gastric volume reduction may provide sufficient efficacy when weight loss is not the major goal of the surgical intervention. METHODS A series of strategies to reduce gastric volume were developed and tested in Long Evans male rats, namely: VSG, Fundal (F)-Resection, Gastric Sleeve Plication (GSP), Fundal-Plication, and Fundal-Constrained. RESULTS All surgical interventions resulted in a reduction of gastric volume relative to sham, but none of the interventions were as effective as the VSG. Gastric volume was linearly correlated to increased gastric emptying rate as well as increased GLP-1 response. Overall, cumulative food intake was the strongest correlate to weight loss and was logarithmically related to gastric volume. Regression modeling revealed a nonlinear inverse relation between body weight reduction and gastric volume, confirming that VSG is the only effective long-term weight loss strategy among the experimental operations tested. CONCLUSIONS The data suggest a minimum threshold volume of the residual stomach that is necessary to induce sustained weight loss. Although all gastric volume interventions increased the GLP-1 response, none of the interventions, except VSG, significantly improved glucose tolerance. In conclusion, if weight loss is the primary goal of surgical intervention, significant volume reduction is required, and this most likely requires excising gastric tissue.

Abstract
Among the bariatric surgery community, it has recently emerged the idea of a possible association between resected gastric volume (RGV) and weight loss after laparoscopic sleeve gastrectomy (LSG). If the size of the sleeve depends on the bougie caliber, the resected volume of the stomach remains something which is not possible to standardize. The aim of the study was to investigate a possible relationship between RGV and weight loss after LSG. We developed a mathematical method to calculate the RGV, based on the specimen size removed during LSG. Ninety-one patients (63 females and 28 males) affected by morbid obesity were included in the study. They underwent LSG between 2014 and 2016. Mean preoperative BMI was 45 ± 6.4. At 1 year after LSG, the mean BMI was 30 ± 5.3 and the EWL% was 65 ± 20.2. The statistical analysis of RGV, BMI, and EWL% at 1-year follow-up did not find any correlation between the volume of stomach removed and the weight loss after LSG. Further studies in the future should clarify the potential role of RGV during LSG. This trial is registered with ClinicalTrials.gov NCT03938025.

Abstract
BACKGROUND We present the correlation between excised specimen size in laparoscopic sleeve gastrectomy and patient demographics, comorbidities, and postoperative weight loss. OBJECTIVE This study aims to address whether the size of gastric specimen excised during laparoscopic sleeve gastrectomy has any correlation with patient demographics, comorbidities, and postoperative percent of excess body weight lost. SETTING Study was performed at a community teaching hospital in Michigan. METHODS We examined data from 204 patients who underwent sleeve gastrectomy between August 2011 and January 2015. Data was collected retrospectively including demographics, comorbidities, body mass index (BMI), percent of excess body weight lost, and the size of the gastric specimen removed including specimen volume in cubic centimeters, length, width, and thickness in centimeters. RESULTS We found that gastric specimen size does not correlate with initial BMI or change in BMI at 3, 6, or 12 months. Larger specimen sizes were found in males, increasing age, and patients with diabetes mellitus. CONCLUSIONS There was no correlation between excised stomach size in laparoscopic sleeve gastrectomy and postoperative weight loss (percent of excess body weight lost) or change in BMI. Male gender, diabetes, and increasing patients' age correlated with larger excised stomach size. Initial BMI and having histological gastritis did not correlate with excised stomach size.

Abstract
Background Our aim is to evaluate the effects of High Resected Gastric Volume(HRGV) on poorly Type 2 Diabetes Mellitus(DM2) after Laparoscopic Sleeve Gastrectomy(LSG). Methods 256 patients were divided into two groups according to the RGV: < 1500 mL(Group A: 131 pts) and > 1500 mL(Group B: 147 pts). % excess body mass index loss (%EBMIL), Fasting Blood Glucose (FBG), HbA1c, C peptide were assessed before surgery and at the 3rd day, 6th,12th,24th,36th month after LSG. Results A significant difference in %EBMIL between the two groups at 24 and 36 months was found. RGV was not significantly associated with DM2 in the multivariate logistic regression. FBG levels showed no differences between the two groups. A significant decrease of Hb1Ac at 6 and 12 months was found in group B. The C-peptide level showed a significant reduction at 6 and 12 months in group B. Conclusion The HRGV may play a role in the regulation of the glucose metabolism in the first year after LSG without influence in poorly DM2 control. Further studies are needed to confirm these findings.

Abstract
Although laparoscopic sleeve gastrectomy is an established operation for severe obesity, there is controversy regarding the extent to which the antrum is excised. The objective of this systematic review was to investigate the effect on perioperative complications and medium-term outcomes of antral resecting versus antral preserving sleeve gastrectomy. MEDLINE, EMBASE, and Cochrane databases were searched from 1946 to April 2017. Eligible studies compared antral resection (staple line commencing 2-3 cm from pylorus) with antral preservation (>5 cm from pylorus) in patients undergoing primary sleeve gastrectomy for obesity. Meta-analyses were performed with a random-effects model, and risk of bias within and across studies was assessed using validated scoring systems. Eight studies (619 participants) were included: 6 randomized controlled trials and 2 cohort studies. Overall follow-up was 94% for the specified outcomes of each study. Mean percentage excess weight loss was 62% at 12 months (7 studies; 574 patients) and 67% at 24 months (4 studies; 412 patients). Antral resection was associated with significant improvement in percentage excess weight loss at 24-month follow-up (mean 70% versus 61%; standardized mean difference .95; confidence interval .35-1.58, P<.005), an effect that remained significant when cohort studies were excluded. There was no difference in incidence of perioperative bleeding, leak, or de novo gastroesophageal reflux disease. According to the available evidence, antral resection is associated with better medium-term weight loss compared with antral preservation, without increased risk of surgical complications. Further randomized clinical trials are indicated to confirm this finding.

Abstract
The stomach may be involved by a myriad of pathologies ranging from benign aetiologies like inflammation to malignant aetiologies like carcinoma or lymphoma. Multidetector CT (MDCT) of the stomach is the first-line imaging for patients with suspected gastric pathologies. Conventionally, CT imaging had the advantage of simultaneous detection of the mural and extramural disease extent, but advances in MDCT have allowed mucosal assessment by virtual endoscopy (VE). Also, better three-dimensional (3D) post-processing techniques have enabled more robust and accurate pre-operative planning in patients undergoing gastrectomy and even predict the response to surgery for patients undergoing laparoscopic sleeve gastrectomy for weight loss. The ability of CT to obtain stomach volume (for bariatric surgery patients) and 3D VE images depends on various patient and protocol factors that are important for a radiologist to understand. We review the appropriate CT imaging protocol in the patients with suspected gastric pathologies and highlight the imaging pearls of various gastric pathologies on CT and VE.

Abstract
BACKGROUND The correlation between resected gastric volume (RGV) and neuro-humoral changes (ghrelin and GLP-1) after laparoscopic sleeve gastrectomy (LSG) and their effects on type 2 diabetes mellitus (T2DM) has been evaluated. MATERIALS Ninety-eight patients were divided in two groups: RGV <1200 mL (group A: 53 pts) and RGV >1200 mL (group B: 45 pts). Insulin secretion (insulin area under the curve (AUC)), insulinogenic index (IGI) and insulin-resistance (homeostasis model assessment, HOMAIR) were assessed before and after surgery (at the 3rd day and 6, 12 and 24 months after LSG) using the oral glucose tolerance test (OGTT). At the same time, ghrelin and GLP-1 levels were determined. RESULTS A significant difference in T2DM resolution rate was observed after 6, 12 and 24 months in favour of RGV >1200 mL. Group B performed better than group A at the 3rd day and at the 6th, 12th and 24th months with regard to AUC, IGI and HOMAIR. In both groups, OGTT resulted in decreased ghrelin values and a significant increase in GLP-1 values for group B at the 3rd day and at the 6th and 12th months with no difference at the 24th month. CONCLUSION Ghrelin and GLP-1 changes play a role in the regulation of glucose metabolism during the 1st year after LSG. RGV influences ghrelin and GLP-1 plasma levels after LSG, with a significant improvement in the T2DM control.

Abstract
PURPOSE To evaluate the feasibility of post-operative CT gastrography for volumetry of the remnant stomach in gastric cancer patients treated with distal gastrectomy. METHODS CT gastrography was performed with oral administration of effervescent granules in 35 gastric cancer patients who underwent distal gastrectomy. Two readers independently rated the degree of gastric distension on a four-point scale, one (near-total collapse) to four (well distended) and measured the volume of remnant stomach using either 3D or 2D volumetry. The inter-volumetry agreements between the 2D and 3D methods and the interobserver agreements between readers 1 and 2 were assessed by intraclass correlation coefficients (ICCs) and Bland-Altman plots. RESULTS The mean score of gastric distension was 3.4 ± 0.6 points and 3.4 ± 0.7 points from readers 1 and 2, respectively. We regarded CT images scored with 3-4 points as a technical success for reliable CT volumetry, which achieved a rate of 91.4% (32/35). For the inter-volumetry agreements between 3D and 2D volumetry, the ICCs were 0.9778 and 0.9814 from readers 1 and 2, respectively. The interobserver agreement between readers 1 and 2 was also excellent, with ICCs of 0.9961 and 0.9876 for 2D and 3D volumetry, respectively. On Bland-Altman plots, the means of differences between any pairs of volumetry measurements ranged from -31.1 to 3.2 cm(3), which may be an acceptable range of measurement variability. CONCLUSIONS Post-operative CT gastrography is feasible in patients treated with distal gastrectomy. Both 2D and 3D volumetry methods are comparable in measuring the remnant stomach volume.

[PMID: 27134194 DOI: 10.1016/j.soard.2016.01.021] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Revised: 12/24/2015] [Accepted: 01/22/2016] [Indexed: 12/13/2022]
Abstract
BACKGROUND Causes of weight loss failure after sleeve gastrectomy (SG) are still controversial. The impact of the size of the sleeve continues to be debated. OBJECTIVE The aim of our study was to determine the impact of sleeve volumes assessed at 3 months using gastric computed tomography (CT) on weight loss at 18 months. SETTING University Hospital, France. METHODS Sixty-seven obese patients eligible for SG were prospectively evaluated. Sleeve volumes were assessed postsurgery using 3-dimensional gastric CT with gas at 3 months and weight loss outcomes recorded up to 18 months. The population was divided into 2 groups: the first tertile (n = 22) with the smallest gastric volume was defined as the "small sleeve" group (SSG) and the rest of the population (n = 45) was defined as the "without small sleeve" group (WSSG). RESULTS No patients were lost to follow-up. In the SSG, overall gastric volume was 133±7 mL versus 264±11 mL for the WSSG (P<.0001). Percentage excess body mass index loss (%EBMIL) during the first postoperative 18 months was significantly greater in the SSG compared with the WSSG (P = .04). Although the volume of the gastric tube was not correlated with weight loss (r =-.04, P = .78), there was a negative linear correlation between the volume of the antrum and the %EBMIL at 18 months (r =-.39, P = .005). A narrow gastric tube was also associated with a high digestive intolerance and reflux. CONCLUSION Our data suggest that performing the sleeve with a not-too-small bougie size and a radical antrectomy could improve weight loss and digestive tolerance.
